Visa open-sources a cybersecurity harness that can plug into any model

Visa has open-sourced a cybersecurity harness for agentic workflows, designed to let users plug in any model—hosted closed, hosted open, or on-prem.
The post’s core point is that the “strength is in the harness, not the model”: Visa is sharing infrastructure that can lift the baseline for defensive cyber work by making the orchestration layer reusable across different model backends.
